(Question)
I got a mix of wild flowers and I am wondering what this is and if it is an Ontario native. Thanks!
(Answer)
Plant identification can be very difficult without seeing photos of the growth habit along with plant stems and leaves, so after much consultation amongst our Toronto Master group, we have determined that your mystery plant is most likely Iberis umbellata, commonly called globe candytuft. Below, you will find a link to a description and more information on this plant.
